À propos

We are seeking a highly skilled Application Security Engineer with strong experience across secure code review, penetration testing, automation, and modern SDLC practices—including emerging AI/LLM security.

You will combine hands‑on technical testing with scalable automation and developer enablement to mature our AppSec program and ensure secure, resilient applications at speed.
